milkdrop has got massive mathematical ERRORS!

check this out- if you write sinus of X axis in milkdrop it actually brings out a massive error-so that if you REALLY want sinus of x you have to write sin(x*6.3) ...so it's roughly 6.3 times wrong in its normal value. it's like saying that I am only 40cm tall.

this is complete nonsense! What's going on! I think it is the same for all the other proportions like radius and angle...

CRAP! Can anyone shed light on this?

 15th July 2007, 14:14 #9 bdrv Senior Member   Join Date: Apr 2007 Posts: 183 no wonder I couldn't get anything straight! My audio program automatically adjusts all the trigonometry to be in between zero and one-because it is also made for fast pretty results like milkdrop, milkdrop should really have variables to fast access all the symmetrical variations of XY axis, at the moment there is x/y/rad but there are at least 10 others which are useful including the diagonal crosses and all that. is confusing enough with all the whole 3D mesh thing anyway.

guess which menu this is...believe it or not it's down to the quality of audio driver directx calls for the M-audio FireWire audiophile

i used to see stuff like that on my old ati rage pro card (was a driver issue from what i remember in the end and a lack of card memory but the driver issue was the main thing causing it)

 27th July 2007, 05:08 #13 bdrv Senior Member   Join Date: Apr 2007 Posts: 183 definitely a software issue. with the dodgy laptop sound card on FireWire, if ever I move a graphics overlay window simultaneously as the milkdrop window, the audio driver stutters and dies and the only way to restart the audio is to switch on my TV card which seems to refresh directx and then the sound comes back. That time it was just all the writing in milkdrop that was garbled-it could definitely be related to the graphics drivers. also i can't adjust volume levels in the soundcard panel while simultaneously playing audio,because it uses a graphics overlay enhanced interface which clashes with the priority level of the sound threads. the only way to stop the sound drivers crashing is to disable any graphics accelerations.-mental.
